*e*^{x} is its own derivative, and therefore its own antiderivative.
This is approximately equal to 1.718, but you should give *e*^{1} – 1 as your final answer, because *e*^{1} – 1 is exact and 1.718 is only an approximation. When the integrand has multiple terms, be careful to keep track of signs correctly. As you work out *F*(*b*) and *F*(*a*), keep parentheses around them so the signs don't get mixed up. |
